IMPROVEMENT IN MEDICINAL CAPSULES.

Specification forming part of Letters Eatent No.'l416,803, dated January 27, 1874; application filed November 22, 1873.

fb all whom fit may concern.'

Beit known that I, PETER CAUHAPE, of the city, county, and State of New York, have invented a new and Ii'nproved Medicinal learl or Capsule, of which the followii'l g is a specification:

My invention consists of round or spherical pearls or capsules, of gelatine or other substance with which medicines are coated to prevent tasting; and it also consists of a tool constructed in a peculiar way, whereby it is adapted for making them round.

Figure 1 in the dra-win g is a side elevation of the said tool. Fig. 2 is a side elevation of my improved pearl. Fig. 3 is a section of a pearl, and a holder in which it is placed to be filled. Fig. 4 is a side elevation of the common capsule.

The method of making the pearl or capsule sacks of gelatine consists of dipping the ball A in the gelatine in a liquid state, of such low temperature that a thin film will adhere to and solidify on the ball when lifted out, sufficiently to form an elastic envelope, which may be pulled od the ball by the lingers, and placed in a mold or holder, D, with the mout-h upward, to be lled with the medicine, after which the mouth is sea-led up.

Heretofore round balls have been used for makingI these little cups or sacks, and the sacks produced have always been elongated7 at i", thus making, when sealed at the top, a

completely round article, which is much better in respect of appearance, and is more acceptable to the public than in the old form. i

The sectional gure of the sack in Fig. 3 shows how the substance accumulating at the bottom produces the round form by thickening the bottom.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a round pearl or capsule, substantially as and for the purpose set forth.

2. A dipping-tool for the manufacture of round pearls, having the bottom nat-tened, as

described.
